Laser scanning system and scanning method for reading bar codes |
(57) A system for reading bar code symbols or the like, having a scanner for generating
a laser beam directed toward a target and producing a narrow first raster scanning
pattern that enables the user to manually aim and direct the beam to the location
desired by the user and a relatively wider second raster scanning pattern that sweeps
an entire symbol to be read, and a detector for receiving reflected light from such
symbol to produce electrical signals corresponding to data represented by such symbol.
